#176 TDC::TStateGuard to restore GDI state at end of scope

Milestone: unspecified

It is possible to use a TDC alias as an improvised state guard, but it would be better to have a dedicated state guard, that simply calls TDC::SaveDC in the constructor and TDC::RestoreDC in the destructor.

See "Selecting and restoring GDI objects in TDC".
